HEADS UP FOR ANYONE ELSE CONSIDERING THIS:
If you are going to receive funds with PayPal and they are going to exceed the 'occasional sale' guidelines (which some people interpret to mean the same guidelines at the rule for sending an IRS 1099 form which is < $600 annually.
First establish your business presence in the US, that means creating an LLC, getting an EIN  and establishing a relationship with a US based bank.
If you get hung up on those steps, don't start taking money with PayPal because their zealous anti-fraud/laundering/drug program fires on a hair trigger. It didn't help that the OP is a student from Venezuela which is not one of America's trading partners.
I expect you will lose most of this money in legal fees. However, if the business is durable, and you manage to establish your LLC (that lawyer you got can help with that) then you will make it back and PayPal will back down. As long as the money trail can be tracked and everyone in the path reports it to the Federal Government so that they are satisfied it isn't part of a laundering scheme, or if it was they can catch the folks involved, you will be ok.
A common misconception among Americans. Though understandable considering the state of diplomatic relations.
"The United States is Venezuela's most important trading partner. U.S. exports to Venezuela include machinery, organic chemicals, agricultural products, optical and medical instruments, autos and auto parts. Oil dominates U.S. imports from Venezuela, which is one of the top four suppliers of foreign oil to the United States. About 500 U.S. companies are represented in Venezuela. U.S. foreign direct investment in Venezuela is concentrated largely in the petroleum, manufacturing, and finance sectors."
It very much is. That's one reason for most of the anti-Venezuelan/Chavez propaganda: to get a puppet government like before to cut US companies better deals.
There are some countries were you can pay but not receive funds and some where you can sell but can't keep any money in your PayPal account (it's automatically transfered every day to you local bank account).
PayPal wants to do business everywhere it can (that's how they make money) and modifies how it does business to meet the laws it must.
So, it can't do business in countries where the US prohibits it (see the OFAC list) as they're a US company and limits account functions where other laws require it.
